"SPEAKER ACTIVE MATCHING,
PORTABLE LABORATORY
SAM Lab
is the latest innovation invented inside Devialet’s acoustical and signal processing
laboratories. SAM Lab
revolutionizes the way speakers are measured.
In 2014, in order to measure and obtain the SAM parameters several days of measurements were
needed with the first speakers Devialet analyzed. The engineers opened these individually, measured
each driver, cross-over filters, and the cabinetwork.
In 2015, thanks to SAM Lab, the same speaker model can now be entirely characterized in less than
8 minutes,. This can be achieved in semiautomatic manner, without having to open the speakers.
SAM Lab is a portable and extremely powerful piece of equipment which will allow Devialet to
accelerate the process of making a speaker SAM Ready, and to reach all the speakers on the
audiophile market.
SAM Lab is composed of three elements:
|
A Devialet Expert 200.
|
The SAM Lab
device: it is placed between the speaker which needs to be modeled and the
Devialet Expert.
|
The SAM Lab software, conducting the three elements, measures everything in a semi-
automatic manner and calculates in real time the SAM V2 parameter set.
The best measuring tool to measure the speakers is therefore Le 200 with the Devialet Expert 8.0
Firmware and an SDcard with a specific SAM Lab configuration. All this is allowed by the powerful
EVO Platform
concept: the Devialet becomes the measuring tool allowing a speaker to become
SAM Ready.
The SAM Lab device, specially designed to interface with Le 200, combines all the connections
required to make a speaker SAM Ready with the laser control system which measures the movement
of the drivers’ membrane.
The SAM Lab software runs on Macintosh and PC. It makes it easy to measure in just a few steps
all the measurements and calculations that are required to characterize a speaker. Devialet specially
developed algorithms able to automatically calculate the key parameters of the speaker."
